ROLL FOR ROLLING HORSESHOE-BLANKS.

SPECIFICATION forming part of Letters Patent No. 406,711, dated July 9,1889. Application filed December 10, 1888. Serial No. 293,108. (Nomodel.)

To all whom it may concern:

Be it known that we, WILLIAM EYN ON and WILLIAM SEAMAN, both citizens ofthe United States, and residents of WVilmington, New Castle county,Delaware, have invented certain Improvements in Mills for Rollingl-Iorseshoe-Blanks, of which the following is a specification'.

The object of our invention is to so construct a mill for rollinghorseshoe-blanks that the continuous bar fed into the mill will berolled into the proper shape for the blanks and severed, so that theblanks issuing from the mill can pass directly to the bending-ma chinewithout any further reheating. This object we attain in .the mannerhereinafter set forth, reference being had to the accompanying drawings,in which Figure 1 isa side view, partly in section, of ahorseshoe-blank-rolling machine constructed in accordance with ourinvention. Figs. 2 and 3 are face views, respectively, of the creasingand finishing rolls of the machine; and Fig. 4 is a perspective viewillustrating the action of the mill.

In Fig. 1, A represents the frame or housing of the mill, havingsuitable guides for the boxes a of the creasing-rolls B andfinishingrolls D and for the boxes of lower or carrying rolls B and D,operating in conjunction with said creasing and finishing rolls,respectively, the upper boxes being acted upon by the usual adjusting-screws l) and the lower boxes being supported by wedge-blocks cl,while bet-ween the'two pairs of rolls is a box or trough F, which servesto support and guide the bar in its passage from one pair of rolls tothe other. The upper or creasing roll B has in the present instance twosets of creasing ribs or projectionsff', of the usual character, so thatit forms two blanks on each rotation of the roll, and between these .twosets of creasing-ribs are projecting fins or blades 9, of such characterthat they will almost, but not quite, sever the bar between thesuccessive blanks or creased portions.

The rolls D D of the mill provide a pass of the usual form for thefinishing of the creased bar; but the rolls D D are so proportioned orare so driven in respect to the rolls B B as to have a slightly greatersurface speed than said rolls B B, so that that :part of the bar betweenthe two sets of rolls It will be evident that in carrying out ourinvention the creasing-roll may be provided with creasing ribs orprojections of such character as to produce but one blank on eachrofation of the roll, in which case but one fin or projection g need beformed on said roll, or the roll may have more than two sets of creasingprojections and more than two severingfins, if desired.

Having thus described our invention, we claim and desire to secure byLetters Patent- 1. The combination, in a mill for rollinghorseshoe-blanks, of the creasing-rolls having one or more fins or projectio'fis for transversely indenting the bar so as to partially severthe same, and finishing-rolls driven at slightly greater surface speedthan the creasing-rolls,

so as to impart a slight draft to the bar and tear it apart at theindented portions, all substantially as specified.

2. The combination of the creasing-rolls having one or moreindenting-fins for partially severing the bar, the finishing-rollsdriven at a great-er surface speed than the creasing-rolls, so as toimpart draft to the bar and pull it apart at the indentations, and aWVM. EYNON. M. SEAMAN.
